All of our windows and doors are built for New Zealand and Australia’s unique weather conditions.
We have especially focused on the strength of each element of our products to ensure long lasting durability and safety. Each unit has been tested to meet NZ Code NZS 4211 for performance of windows and to the glass and glazing standard NZS 4223.
Designed for the real world, by the people who have been making and installing windows and doors for 30+ years, our products are created for life.
